The ax25-apps package contains programs for the hamradio protocol AX.25 that would be used by normal users (as opposed to network daemons). While not essential, these programs are usually installed if you want to connect to amatuer packet radio networks. Generally it is a good idea to also get the ax25-tools package so you can configure the hamradio ports. This package includes call, listen, ax25ipd and ax25rtd.

The ax25-tools package contains the tools that you need to get going with AX.25 for Linux. AX.25 is a network protocol that is used by hamradio operators across packet radio wireless links. This package contains the network tools to configure hamradio interfaces and some of the hamradio specific network daemons. In addition to programs that understand AX.25, they also work with ROSE and Net/ROM hamradio protocols.

Baudline is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail. Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters. The baudline signal analyzer combines fast digital signal processing, versatile high speed displays, and continuous capture tools for hunting down and studying elusive signal characteristics.

DXSpider is a Ham Radio program that connects to other similar programs by radio or the internet and provides a real-time information service to Ham Radio operators rather like IRC. It is designed to become a complete replacement for the original DOS implementation written by Dick Newell AK1A.

icq7com is a utility for the Icom IC-Q7 mini handheld transceiver. It enables complete backup of its memory, downloading, editing and uploading of channels. This package is useful mostly for HAM radio operators.

The libax25 package has a set of functions making it easier to write hamradio programs. The functions cover most of the types of hamradio addresses (AX.25, ROSE & Net/ROM) as well as understanding the hamradio port parameters.

sctl is used to control the Bearcat BC895xlt, BC245, BC780, and Radio Shack PRO-2052 trunk tracking scanners. It can read and set memory contents and a numerous settings, and will display and change the current status (e.g. scanning, trunk scanning, etc.). It can also download/store and upload memory bank contents.

TNT is a packetradio terminal for use with hostmode TNC (or tfkiss) and ax25-kernel. It was originally developed by Mark Wahl. TNT works on Linux, Solaris and NetBSD. Actually is should also run on DEC Alpha, since most routines were converted to 64-Bit.
